Hello, I have a dataset that reads data feom a Dataflow on Powerbi services and the other Datasource is a list on Sharepoint.

When refreshing on my Desktop,everything is fine while when we refresh on PowerBi services, we are getting this message:

Hi. This error sounds like a privacy level issue. Please go to the dataset settings and Edit Credentials for the sources. Make sure they have the same privacy level (except for private). I would recommend all in organizationl, but you can have them both as none or both as public.

If the privacy level doesn't match, Power Query can't combine differente sources. Desktop will let you depending the configurations you have for your environment.

I hope that helps,
